Add a default 4 KiB ashift for Amazon EC2 NVMe devices on instances with
|
|
NVMe ephemeral devices, such as the types c5d, f1, i3 and m5d.
|
|
As per the official documentation [1] a 4096 byte blocksize should be
|
|
used to match the underlying hardware.
|
|
|
|
The string was identified via:
|
|
|
|
$ sudo sginfo -M /dev/nvme0n1
|
|
INQUIRY response (cmd: 0x12)
